"Loose buds:" What do you mean by that? Do you mean the buds are not turning rock hard, that they remain loose and airy, not congealed/junked together? [If you want dense(r) buds, presuming there are enough surface trichomes, you can alway just press the buds together in your hand after harvesting and trimming].
What is wrong with loose buds? Are dense(r) buds actually better in your view (in terms of what: yield, potency, quality of high)?
I often get loose buds, but the yield and quality are the same (maybe better), so I see no problem. Otherwise, sativa strains often naturally tend to grow looser, more airy buds. Looser buds theoretically allow a lot more surface light exposure vs. dense buds; should be more potent. Outdoor growers generally want loose(r) buds, with these much less susceptible to mold, bud rot.
The little I can see in the pictures, the buds look normal.
